I run a Meteor on location, and just finished a couple flipper repairs on it. A day later, I'm working on the game next to it and I notice a few new issues.

First of all, I'm missing the last beep in the startup sequence, but the game will still start.

Then the credit switches were not adding credits, even though the switches worked in test.

Then I press the start button with zero credits and it adds 99 credits and starts a game! This is new. I am not using free play roms. I am using /10 roms though.

I noticed that it was displaying the high score to date as "6 6 6" . It was also displaying those 6s in some of the audits.

Also, the sound is acting very strange. The spinner makes no sound at all, and the bumpers are making sounds I've never even heard on this game, along with some other weirdness. Also adding a credit or starting a game plays a startup tone along with the usual sounds.

I cleared the audits with the weird numbers, started it back up, and now it will accept credits and start games properly... ok..

Of course this didn't solve the sound issue. I know these problems would probably usually be diagnosed as the symptoms of more than one thing, but I just thought it odd that they both came up simultaneously..

Thanks!

So I ordered 2 "5101 CMOS RAM IC" chips from Action Amusements. Installed them and the game wouldn't even boot. Ok, so wrong chips I guess.

Reinstalled the old chips and now it works perfectly. Thoughts?
